Abstract

Manganese pnictides MnP, MnAs, and MnSb are ferromagnetic semimetals and have some unique properties, namely, high Curie points, considerable magnetic anisotropy, and giant magnetocaloric effect. Experimental and theoretical studies showed that these compounds can enter a superconducting state under high external pressures. Manganese pnictides are widely used in design of hybrid structures, such as spin diodes and transistors, in combination with semiconductors. The survey focuses on the design and properties of such the structures.
